Try using the other way of escape (there are 2 ways) and don't miss anything you can click on, after that just don't resist
There are two exists which the game tells you at the start of the dungeon and labelled as (!) for you to know. You can either go an easy way and fight through a bunch of moles/wait until the moles knows you've escaped (you spent too much time) or do some "water works" to be able to go through the other one.
Goodluck, I can't spoil more from here.
There's a small room that's labeled as "Office" with a giant mole inside. So anyway, when you start the dungeon there will be an encounter with some moles that will ask you what kind of worker you are cause you're new (if I remember correctly) , just choose the option that you are a "sus" one and then keep moving on from then til you reach the office to get your work permit registered.
You know you are one when the supervisor mole takes you to some private do some "alone time" with him but then got interrupted.
